Blackberries are very perishable with a limited shelf life due to high metabolic activity and susceptibility mechanical damage microbial attack. The effect of edible coatings (EC) based on candelilla wax (CW) guar gum (GG) the quality, life, bioactive-compounds content antioxidant blackberries stored at 25 ± 2 °C for 6 days, was evaluated. All EC contained GG (0.4%) gallic acid (GA)(0.06%); EC1...

Tomato (Solanum lycopersicum L.) is a glycophyte species with medium sensitivity to salts, tolerating electrical conductivity values in the soil solution of up 2.5 dS m-1. Silicon (Si) beneficial element that can act as an inorganic biostimulant plants subjected salinity. In this research, main effects two study factors were evaluated: a) salinity by NaCl (0, 50, and 100 mM) nutrient b) biostim...

Mechanical damage is a threat to both food security and sustainability. Bruising the most common type of mechanical damage, it causes huge economic loss due rejection fresh produce downgrading appearance quality by consumers. Therefore, this study aims examine effect bruising during postharvest handling using pendulum test technique. Pomegranate fruit were bruised once at two impact levels (1.1...

Penicillium digitatum and P. italicum are the major postharvest pathogens in citrus. To reduce decay, use of low-oxygen (0.9 kPa O2) (LO) or low-pressure (6.6 kPa) (LP) treatments were evaluated during storage navel oranges for four eight days. The results showed that exposure to both LO LP reduced vivo pathogen growth compared untreated (UTC) oranges, with being most effective. effects on frui...

In this study, we describe the synthesis of zinc oxide nanoparticles (ZnO NPs) and evaluate impact alginate-based ZnO NPs (Alg–ZnO on microbiological activity, storage behavior, physico-chemical properties ‘Kiett’ mango fruit. The fruits were coated with alginate Alg–ZnO then stored at 13 °C; uncoated used as controls. synthesized characterized, confirming formation spherically shaped particles...

This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...

softening and microbial activity are the most common problems of kiwifruit during storage. in order to improve these problems, pre- harvest treatments of putrescine and spermidine were studied on shelf life of kiwifruit cv. hayward. foliar spraying of different concentrations of purescine (0, 1 and 2 mm) and spermidine (0, 1 and 2 mm) has been done at 40 and 20 days before harvest. different ch...
